For the record I am pretty sure someone from Dybex (not Bones) told them it would be live action when they asked for more information about the movie. It is entirely possible that Dybex has incorrect information. It also might be possible that these two girls misunderstood.

I really don't think they are making this up though.

However I remember a similar thing happening with the number of episodes. A European magazine stated the series will be 63 episodes when there was no confirmation from Japan and others including US distributors said the info was false. In the end the series turned out to be 64 episodes but I believe it was scheduled for 63 episodes until the last minute.

Thus sometimes these type of rumors can turn out to be true. But of course we should take it with a grain of salt until we hear an official announcement from Japan.
